Sprint has said today that they will stop selling smartphones and modems that are compatible with Clearwire's WiMax 4G at the end of 2012.
The carrier is expected to transition to its own higher-speed 4G network at that time.
Following the move, Clearwire's stock fell to an all-time low at $1.32, down 30 percent from yesterday.
Sprint is by far Clearwire's largest customer and Sprint is a majority owner of the 4G network.
President of network operations, Steve Elfman, says Sprint's own 4G network will be as large as Clearwire's by the end of 2012, and significantly larger by the end of 2013.
Sprint is moving to LTE, the same network spectrum used by AT&T and Verizon.
